Because many of the original materials of the storm bottle have been scattered, no one knows how the original formula was, and even who the inventor is is no longer available. However, this invention was improved by many scientists in the 19th century. In the "R&D history" of the Storm Bottle, the most noteworthy person is Captain Robert Fitzroy. It was the three-masted sailing vessel "Beagle" he commanded that took Darwin to the famous Global survey. What is relatively unknown is that Captain Fitzroy is also a meteorologist, and he does a lot of weather forecasting and monitoring work. Fitzroy also determined the basic formula of the storm bottle: distilled water, ethanol, camphor, potassium nitrate and ammonium chloride, and used it in the voyage of the Beagle.
According to records at the time, people believe that the storm bottle of this formula can predict various weather conditions such as sunny, cloudy, storm, heavy fog, and snow.
The change of the crystal in the bottle can only reflect the change process of the ambient temperature, while other key indicators (such as air pressure & humidity) cannot. If you really want to predict the weather, it is recommended that you listen to the weather forecast issued by the weather station.
